Louise Henriette Foucar was born May 31, 1864 to Louis and Mary Magdalena (Webber) Foucar. Louis' great-grandparents Isaac and Anne (Boulle) Foucar had been Huguenot refugees from Proissy, Picardy, France, 1698, to a town in the Hessen-Nassau area of Germany. Louise had visited her Foucar cousins there in 1895-96 and maintained a lifelong correspondence.
Her father's journal, in French, describes his emigration in April 1855. Mary came from Bavaria at that time and they were married on November 25, 1855. Louis' journal also records his formula for varnished (patent) leather. The Louis Foucar Leather Factory, built in North Woburn, Massachusetts in 1884, was the basis of the family prosperity.
Because Louise had considerable health problems, in 1884, her parents built a home a few miles north of Boston in North Woburn. Still very ill with respiratory problems, she lived in EI Paso, Texas, then Mexico City. Since Colorado was known to have a healthful climate, in September 1890 she enrolled in the University of Denver.
Louise made lasting friendships at the University of Denver as shown by the many letters and visits to her over a fifty-year period. During her undergraduate days, she had become a member of Pi Beta Phi, and she found in her sisters an extended family. She was a district officer after graduation and helped to establish the chapter here. She even built an addition to her Tucson home as a meeting room. Arizona Alpha chapter was established August 1, 1917.
